类金刚石碳（DLC）可以有效地涂覆在聚合物表面，以改性聚合物的高度功能化的材料。类金刚石薄膜具有高硬度、耐磨性和生物相容性等优异的物理性能，在工业上有着广泛的应用。另一方面，聚合物可以通过选择或控制它们的分子结构来制造柔软，灵活，高吸收性和成本效益的材料。涂覆在这种聚合物基底上的DLC膜已经被研究和广泛使用，因为最近，已经提出了聚合物-DLC复合材料在例如气体阻隔膜和生物相容性医疗装置中的相当多的应用。本文在总结类金刚石膜和聚合物的基本原理的基础上，讨论了类金刚石膜包覆聚合物的阻隔性能，特别是气体阻隔性能和生物相容性，并对类金刚石膜与聚合物的粘附和断裂行为进行了解释，这对创建新型聚合物-类金刚石膜复合材料至关重要。(C)2011 Elsevier B.

Diamond-like carbon (DLC) can be effectively coated on polymer surfaces in order to modify polymers for highly functionalized materials. DLC films have been widely used for many industrial applications due to their outstanding physical properties such as high hardness, wear resistance and biological compatibility. Polymers, on the other hand, can create soft, flexible, highly absorbent and cost-effective materials by selecting or controlling their molecular structures. The DLC films coated on such polymer substrates have been investigated and extensively used because recently, quite a few applications of the polymer-DLC composites to e.g. gas barrier films and biocompatible medical devices have been proposed. In this article, we discussed the barrier properties, especially the gas barrier properties and the biocompatibility of DLC-coated polymers, after summarizing the fundamentals of DLC and polymers, followed by the explanation as to the adhesion and fracture behavior of DLC and polymers, which is crucial for the creation of a new polymer-DLC composite.
